Ulrich, my guts tells me that you will be happy with the Dv8tor if you can find one, I'm sure you can but as back up plan getting yourself a Turbinator, if you really like to build Mr: Ziroli really makes them easy to build, the Dv8tor is big and the P-80 will push it just fine but it will not be a hot vertical zipy faster on the othe hand the Turbinator been an over all weight of 22/24 Lbs the P-80 should be more than enough to get your heir standing by the performance of it.

Good luck with your choice and please post pictures of your winter project for us to see.
